Configure the S1, S2,
and S3 switches according to the following guidelines and save all your
configurations:

Configure the switch hostname as indicated on the
topology.

Disable DNS lookup.

Configure an EXEC mode password ofclass.

Configure a password ofciscofor console connections.

Configure a password ofciscofor vty connections.

Task 2: Configure the Ethernet Interfaces on the
Host PCs

Configure the Ethernet interfaces
of PC1, PC2, PC3, PC4, PC5, and PC6 with the IP addresses and default gateways
indicated in the addressing table.

Task 3: Configure VTP and Security on the
Switches

Step 1.
Enable the user ports on S2 and S3.

Configure the user ports in
access mode. Refer to the topology diagram to determine which ports are
connected to end-user devices.

S2(config)#interface fa0/6

S2(config-if)#switchport mode access

S2(config-if)#no shutdown

S2(config-if)#interface fa0/11

S2(config-if)#switchport mode access

S2(config-if)#no shutdown

S2(config-if)#interface fa0/18

S2(config-if)#switchport mode access

S2(config-if)#no shutdown

Step 2.
Check the current VTP settings on the three switches.

Use theshow vtp statuscommand to determine the VTP operating
mode for all three switches.

VTP allows the network
administrator to control the instances of VLANs on the network by creating VTP
domains. Within each VTP domain, one or more switches are configured as VTP
servers. VLANs are then created on the VTP server and pushed to the other switches
in the domain. Common VTP configuration tasks are setting the operating mode,
domain, and password. Note that all three switches are in server mode. Server
mode is the default VTP mode for most Catalyst switches. In this activity, you
will be using S1 as the VTP server, with S2 and S3 configured as VTP clients or
in VTP transparent mode.

Step 3.
Configure the operating mode, domain name, and VTP password on all three
switches.

Set the VTP domain name toLab4and the VTP password tociscoon all three switches. Configure S1 in
server mode, S2 in client mode, and S3 in transparent mode.

S1(config)#vtp mode server

Device mode already VTP SERVER.

S1(config)#vtp domain Lab4

Changing VTP domain name from NULL to Lab4

S1(config)#vtp password cisco

Setting device VLAN database password to cisco

S1(config)#end

S2(config)#vtp mode client

Setting device to VTP CLIENT mode

S2(config)#vtp domain Lab4

Changing VTP domain name from NULL to Lab4

S2(config)#vtp password cisco

Setting device VLAN database password to cisco

S2(config)#end

S3(config)#vtp mode transparent

Setting device to VTP TRANSPARENT mode.

S3(config)#vtp domain Lab4

Changing VTP domain name from NULL to Lab4

S3(config)#vtp password cisco

Setting device VLAN database password to cisco

S3(config)#end

Note: The VTP domain name can be
learned by a client switch from a server switch, but only if the client switch
domain is in the null state. It does not learn a new name if one has been
previously set. For that reason, it is good practice to manually configure the
domain name on all switches to ensure that the domain name is configured
correctly. Switches in different VTP domains do not exchange VLAN information.

Step 4.
Configure trunking and the native VLAN for the trunking ports on all three
switches.

On all switches, configure
trunking and the native VLAN for FastEthernet interfaces 0/1-5. Only commands
for fa0/1 on each switch are shown below.

Here you
see one of the advantages of VTP. Manual configuration is tedious and error
prone, and any error introduced here could prevent intra-VLAN communication. In
addition, these types of errors can be difficult to troubleshoot.

Step 10.
Configure the management interface address on all three switches.

S1(config)#interface vlan 99

S1(config-if)#ip address 172.17.99.11 255.255.255.0

S1(config-if)#no shutdown

S2(config)#interface vlan 99

S2(config-if)#ip address 172.17.99.12 255.255.255.0

S2(config-if)#no shutdown

S3(config)#interface vlan 99

S3(config-if)#ip address 172.17.99.13 255.255.255.0

S3(config-if)#no shutdown

Verify that the switches are
correctly configured by pinging between them. From S1, ping the management
interface on S2 and S3. From S2, ping the management interface on S3.

Were the pings successful? If
not, troubleshoot the switch configurations and try again.

Step 11.
Assign switch ports to VLANs.

Refer to the port assignment
table at the beginning of the activity to assign ports to the VLANs. Since
Packet Tracer 4.11 does not make use of theinterface
rangecommand, only configure
the first interface for each VLAN. Port assignments are not configured through
VTP. Port assignments must be configured on each switch manually or dynamically
using a VMPS server. The commands are shown for S3 only, but both S2 and S3
switches should be similarly configured. Save the configuration when you are
done.
